One of the rooms that you can end up in when playing Ketchcrash is the ether storage room. There will be some purple glowing tanks around the room that are immune to normal damage from guns. The objective requires that you destroy these, here’s how.
To destroy the tanks, you will need to look out for the elite bots that have a diamond icon above them. When you destroy these bots, they will drop explosive charges. Pick these explosive charges up and throw them at the purple tanks to make them explode.
